To aZL whom it may concern; The peculiar form of tooth caused by the Be it known that 1, JAMES SNOW, of Clevechamfering commencing part way down the land, in the county of Cuyahoga and State of tooth has marked advantages, to wit: The Ohio, have invented certain new and useful tooth, being left full size at the base and far Improvements in Belt-Fasteners; and I do enough to extend nearly through the belt, is

The advantages of the pushed on through the belt without injuring 5 chisel-edge are well known, to wit: They the latter, in case the belt is not to be taken 5 make a clean cut through the belt without up. If the belt requires shortening, of course tearing the fiber thereof, and clinch down the end having the clinched teeth therein is easily with the fiat side flush and smooth with cut off. In either case, by supplying new teeth the surface of the belt, the rounded side of to this end of the plate the loose end of the 50 the tooth being embedded in the belt. belt may be again fastened. If the belt has I00 been taken up, of course the new teeth puncture new holes in the belt; otherwise the new teeth enter the old holes in the belt. v a

In making the splice, in the first instance, the two ends of the belt are abutted together and the fastener is placed centrally over the joint and driven down until the teeth pass through the belt and the belt rests firmly against plate A. The teeth are then clinched and hammered down flush with the face of the belt, the teeth in clinching being always bent inward or toward the center line of the belt-fastener.

Points or marks a on the back of plate A serve as guides in placing the plate over the splice or joint of the belt.

WVhat I claim-is- In a belt-fastener, a plate having one or more teeth integral therewith and projecting from one side thereof, and one or more detachable teeth each having an angular portion adapted to be removably secured in an angular opening formed in the plate, the rigid and detachable teeth each having a chamfered side, the said chamfer commencing midway of a tooth and extending to the point thereof, and located on the side of the tooth opposite to where the draft of the belt comes, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this 18th day of April, 1888.

JAMES SNOW. Witnesses:
